mcp

Overview

mcp.rs is a comprehensive Rust implementation of the Model Context Protocol that enables high-performance, type-safe communication between AI applications and their integrations. It supports multiple transport types including stdio and HTTP with SSE, offers robust resource management, and provides flexible configuration options through YAML/JSON files, environment variables, and command-line arguments. The implementation follows a modular architecture with clear separation of concerns between transport, protocol, resource, and configuration layers.
